CAR-COUPLING.,`

SPECIFICATION forming part of Lettersuilatent No. 509,993, dated December 5,1893.

Application ledSeptem'ber 25, 1893. `Serial 110.4361375 (No model.)

To aZZ whom tm/tty concern/.- Be it known `that I, MARTIN ZIMMERMAN, citizen of the United States, residing at Jeromesville, inthe county of Ashland and State of Ohio, have invented certain new and use` ful Improvements in `Car-Couplings, of which the following is a full, clear, and exact description.

My invention consists of a bi-chambered draw-head provided with an automatically actuated pin and tongue for securing the link by means of which two cars are coupled together.

The object of `my improvement is to provide a coupling for cars which is manipulated au`` tomatically without danger to the person op` erating the same. l That my invention may be seen and fully understood by others, reference will be had to the following specification and annexed ,t drawings, forming a part thereof, in which- Figure 1 is a side view of my device, the pin being elevated; Fig. 2, an end view showing the pin and tongue depressed, with the link in place; Fig. 3, a top view` with the link in position; Fig. 4, a side view of the pin and tongue with their actuating mechanism, one side of the drawhead being removed to ex hibit the same, and Fig. 5, an opposite side view of thepin and tongue, depressed, with the actuating mechanism and a'portion of a link held in place by said pin and tongue.

Similar figures of reference designate like parts in the drawings and specification.

The draw-head 1 is provided with thetwo chambers 2 and 3, the former above the latter. In the upper part of the chamber 2 is the beam 4 rigidly attached, near its rear end,

to the shaft 5, said shaft bearing in the sides of said chamber. The head of the pin 6 is pivotally connected to the forward end of the beam 4 by means of the link 7 and the pins 8, 8. Back of the link 7 in the beam 4 is the openin g 4a and the pin 9 extends through said opening and projects on both sides of said beam to receive the upper terminals of the prop` 10. The elongated link 11 connects the beam pin 9 withthe pin 12, let into a recess in the tongue 13, or said link may be connected with said tongue in any other suitable manner. The stiff spring 14 passes over the top of the beam 4 where it is held in place by the staple 14a and, after being wound around the shaft 5 several times each side of said beam, terminates in the straight portions 14", 14".

The chain 15, shown in Figs. 1 and 2, eX-

tends from the upper part of the link 7 to the topof the car or other convenient locality and is for the purpose of elevating the beam 4, as hereinafter fully described.

On each side of the interior chamber 2 are the slides 16, 16 vresting on the floor of said chamber, of essentially the form shown in the drawings. The forward ends of the slides 16, ldproject through openings in the front of the `draw-head1 and the recesses 2a, 2 are provided in the rear walls of the chamber 2 toreceive the rear ends of said slides when forced back. Each slide 16 has the notch 16a indented in the under side at the rear. The rods 17, 17 connect the slides 16, 16 with the spring terminals or straight portions 14b 14h. Between the slides 16, 16 are the ways 18, 1S inclined from before, upward and backward. The :pase of the prop lO rests upon the ways 18, 1

In the rearof the chamber 2 beneath the ends of the slides 16, 16 is the shaft 19 having the cams 20, 2O upon opposite ends thereof and the rear upwardly extending terminals of said slides rest upon saidcams.

Suitable openings are provided in the top and bottom of the chamber 3 and in the tongue 13 for the passage of the pin 6 when said pin is depressed, as shown in Fig. 5. The tongue 13 is pivoted at 22 to the sides of the chamber 3 and the free terminal of the spring 23 bears upon the top of said tongue retaining the same in its normal or depressed position. The rear end of the spring 23 is secured tothe top of the chamber 3 at 24 and has an opening therein for the link 11 after said link has passed through a suitable hole in the door of the chamber 2.

The operation of my device is as follows: The pin 6 being elevated in the draw-head 1, as shown in Figs. l and 4, another draw-head, having the link 25 inposition, strikes the projecting ends of the slides 16, 16 and at the same time said link passes into the chamber 3 beneath the lower end of said pin. The notches 16a, 16h in the slides 16, 16 engage the cams 20,20, as illustrated in Fig. 4, when said y slides are fforward; hencevwhen they are forced back said cams rotate and elevate the rear terminals of the slides until a half revolution of the cams. takes place and the slides drop down into position again with their ends in the recesses 2&2. slides '16, 16 are elevated by the cams 20, 2O the base of the prop 10 is carried up on the inclined ways 18, 18 and the shaft 5 is caused to rotate through the medium oi' the spring 14.and the rods 17,1,75thus plunging the beam 4 downward with the pin 6. The sudden lowering of the beam 4. releases the tongue 1.3 which drops, under thenforce of the lspring 23, with the pin 6 and serves as a guide forsaid pin aswell asre'taining they link 25V in a horizontal position, when the opposite end of said linkis'disconneeted, so that it is Aalways in a suitable positionto enter the Iopposite draw-head. The `,severalparts are now in the 'positions indicated in Eigs. 2, Sand 5. To release the link 25 draw up the beam 4 and the pin 6. by means Y' Aotithe chain 15 andtheY link 7. When the beam .4 is nelevated the shaft y is rotated and the slidesl 16, y16 are forced forward by `the spring 14 and therods 17, 17 until the-notches 16., 16 again engage the cams 20, 20. The

, tongue n13 is elevated with the beam 4 by the link 11 andthe base ot' the prop lOslideS down the ways 18,18 until said prop stands nearly perpendicular beneath said beam which is supported thereby. Y f. .a The spring 14 is usedv in place4 of rigid connectionsbetween the shaft 5 andtherodsl, a ldino'rder to prevent injury to the pinandtongue-actating mechanismpby the shock resulting from the contact between two drawheads. l

What I claim as. my invention, and desirel to secure by Letters Patent, is-

As the i y, 1. In `a car coupling, a vbi,chambered, re-

"cessed, perforated draw-head, a shaft and the beam 4 rigidly attached to said shaft, a pin pivotally connected to the free terminal of said beam, the prop pivoted to the beam, and the spring 14havingthe straight portions 14h, 14h, in combination with the shaft 19, the cams 20, on said shaft 19, the notched slides 16, 16, the rods connecting said slides with the spring terminals, and the ways 18, 18, in the manner substantially as and for the purpose set forth. 2Ina car coupling, a bi-chambered, perforated draw-head, a spring-actuated, perforated tongue piyoted withinthe lower chamber of saiddraw-lieamand tliedinl;1 1l connecting said tongue with the beam 4', i n combination with Ysaid. beam rigidly attached to a shaft, the prop 1Q, and .theways 1 8; ,18, in the manner substantially as and for thepurpose setgfo'rth'.
